Takashi Tateishi

Takashi Tateishi (立石 孝) (better known by his alias, Ogeretsu Kun) is a former Capcom sound designer, having created music and sound effects for only a handful of titles before he left the company. He is best known for his work on the Mega Man series, as he composed the music for Mega Man 2, which introduced the series' stage clear jingle as well as the titular character's main theme.

Tateishi is one of the sound team members who engaged in a sort of "secret deal" made possible by close workspace arrangements. During a slump in Mega Man 2 composition, Manami Matsumae contributed eight bars to Air Man's stage theme because her workspace was next to Tateishi's. Tateishi would later return the favor by composing the Forest Stronghold theme, a fan favorite, for U.N. Squadron. Yoshihiro Sakaguchi, who acted as their manager, was aware of these and other instances from other sound members.

Outside of Capcom he has produced music for the Tokimeki Memorial series - where he helped found Shiori Fujisaki, the first virtual idol - under the alias Takashi Kasugano (流石野 孝) but now serves as a sound programmer and coordinator for various Konami titles. He has also opened Most Company, his own studio, where he serves as a music producer for Mami Kingetsu and Motoyoshi Iwasaki.
